AWS CloudFormation template security group viewer

Almost any AWS CloudFormation template are more then long enough. It's OK when you are dealing with different relatively "static" resources but become a big problem for something way more dynamic like security group.
This kind of resource you need to modify and review a lot, especially if you cloud security professional. Reading AWS CloudFromation template JSON manually makes your life miserable and you can easily miss bunch of security problems and holes.
My small aws_secgroup_viewer Python program helps you to quickly review and analyse all security groups in your template.
